ASD儿童对时/体形态的理解通过多模态优先注视（IPL）进行评估，以确定该人群产生这些语素的困难是否延伸到他们的理解。四岁的参与者接受了两次评估，间隔四个月。他们观看了一段视频，视频中并排呈现了正在进行的和已完成的事件，并配以熟悉的动词，动词具有过去式和进行形态。他们的眼球运动被记录下来并离线编码; IPL测量包括观看时间的百分比，以及第一次看匹配场景的延迟。自发的语音样本也被获得，并编码的单词，过去式，和渐进的变化。相对于他们的基线偏好，这些患有ASD的四岁儿童在两个语素的匹配场景中看得更快，时间更长。孩子们谁产生更多的话，进步，过去的词素，以及谁表现得更好的标准化语言评估，表现出更好的理解-ing。总体而言，这些自闭症儿童表现出一致的理解语法方面形态，此外，他们的理解程度被发现与自发生产和标准化考试成绩。
The comprehension of tense/aspect morphology by children with ASD was assessed via Intermodal Preferential Looking (IPL) to determine whether this population's difficulties with producing these morphemes extended to their comprehension. Four-year-old participants were assessed twice, four months apart. They viewed a video which presented side-by-side ongoing and completed events paired with familiar verbs with past tense and progressive morphology. Their eye movements were recorded and coded offline; the IPL measures included percentage of looking time at, and latency of first look to, the matching scene. Spontaneous speech samples were also obtained, and coded for number of words, past tense, and progressive inflections. Relative to their baseline preferences, these four-year-old children with ASD looked more quickly to and longer at the matching scene for both morphemes. Children who produced more words, progressive, and past morphemes, as well as who performed better on standardized language assessments, demonstrated better comprehension of –ing. Overall these children with ASD demonstrated consistent comprehension of grammatical aspect morphology; moreover, their degree of comprehension was found to correlate with spontaneous production and standardized test scores.
